Synthesis of B,B-dinor-B-secosteroids as potential cardenolide analogues
摘要:
A novel chemical construction of B,B-dinor-B-secosteroids as simplified cardenolide analogs, starting from the Hajos-Parrish diketone was developed. The synthesis of the equivalent of the steroid A ring was carried out through a Diels-Alder reaction between an appropriate hydroindenyl acrylate derivative and Danishefsky's diene.
